\frac{2\pi}{3} radians is equal to 90°.

Step-by-step explanation:

Step 1:

If an angle is represented in radians, it will be of the form \frac{\pi}{x} radians.

If an angle is represented in degrees, it will be of the form x°.  

To convert radians to degrees, we multiply the radian measure by \frac{180}{\pi}.

For the conversion of radians to degrees,

the radians in degrees = (given value in radians)(\frac{180}{\pi}).

Step 2:

To convert  \frac{2\pi}{3},

\left(\frac{2 \pi}{3}\right)\left(\frac{180}{\pi}\right)=(2)(60),

(2)(60) = 120.

So \frac{2\pi}{3} radians is equal to 120°.

Calculate the value of P and of Q that satisfy the following simultaneous linear equations.
luda_lava [24]

  1. 0.5p -3q =11
  2. 5p +6q =2

1) ×-2

--> 3. -p +6q =-22

2) - 3)

6p =24

p =4

sub into 2)

5(4) +6q =2

20 +6q =2

6q =2 -20 =-18

q=-3
